Advantages

Convenience: Ecommerce can occur 24 hours a day, seven days a week. Although ecommerce may take a lot of work, it is still possible to generate sales as you sleep or earn revenue while you are away from your store.

Increased selection: Many stores offer a wider array of products online than they carry in their brick-and-mortar counterparts. And many stores that solely exist online may offer consumers exclusive inventory that is unavailable elsewhere.

Potentially lower start-up cost: Ecommerce companies may require a warehouse or manufacturing site, but they usually don't need a physical storefront. The cost to operate digitally is often less expensive than needing to pay rent, insurance, building maintenance, and property taxes.

International sales: As long as an ecommerce store can ship to the customer, an ecommerce company can sell to anyone in the world and isn't limited by physical geography.

Easier to retarget customers: as customers browse a digital storefront, it is easier to entice their attention towards placed advertisements, directed marketing campaigns, or pop-ups specifically aimed at a purpose.
